## Cmd-R does not reload the simulator
|
|
Enable iOS simulator's "Connect hardware keyboard" from menu Hardware > Keyboard menu.
|
|
|
|
|
|
|
|
|
|
If you are using a non-QWERTY/AZERTY keyboard layout you can use the `Hardware > Shake Gesture` to bring up the dev menu and click "Refresh"

## Port already in use red-screen
|

|
|
|
|
|
|
Something is probably already running on port 8081. You can either kill it or try to change which port the packager is listening to.
|
|
|
|
### Kill process on port 8081
|
|
`$ sudo lsof -n -i4TCP:8081 | grep LISTEN`
|
|
|
|
then
|
|
|
|
`$ kill -9 <cma process id>`
|
|
|
|
|
|
|
|
### Change the port in Xcode
|
|
Edit `AppDelegate.m` to use a different port.
|
|
```
|
|
// OPTION 1
|
|
// Load from development server. Start the server from the repository root:
|
|
//
|
|
// $ npm start
|
|
//
|
|
// To run on device, change `localhost` to the IP address of your computer, and make sure your computer and
|
|
// iOS device are on the same Wi-Fi network.
|
|
jsCodeLocation = [NSURL URLWithString:@"http://localhost:9381/index.ios.bundle"];
|
|
```
